This specification covers precipitation hardened iron base superalloy forgings which are primarily intended for use as turbine rotor disks and wheels. Two heat treatments are covered and selection will depend upon design, service conditions, mechanical properties, and elevated temperature characteristics. The material shall be made by vacuum melting followed by consumable electrode vacuum arc or electroslag remelting. The forgings shall undergo the following tests: tension test, hardness test, stress rupture test, and creep test. Also, the forgings shall be subjected to non-destructive examinations like ultrasonic examination and liquid penetrant examination. The forgings shall be uniform in quality and condition, clean, sound, and free of cracks, seams, laps, shrinkage, and other injurious imperfections.
